(Cl. l03218) 3 Claims.

This invention relates to supporting devices, and more particularly to asupporting device for pumps of the vertical centrifugal type.

One object of the invention is to effect a rigid connection between thepumping mechanism and the support therefor, and

Another object is to enable th pumping mechanism and the supportingdevice to be expeditiously connected to and disconnected from eachother.

Other objects will be in part obvious and in part pointed outhereinafter.

In the drawings accompanying this specification and in which similarreference numerals refer to similar parts.

Figure 1 is a side elevation of a supporting device constructed inaccordance with the practice of th invention and a pumping mechanismsecured thereto,

Figure 2 is an elevation, partly in section, of

the supporting device and portions of the pumping mechanism,

Figure 3 is a top plan view of a detail, and

Figures 4 and 5 are perspective views of details of the supportingdevice.

Referring more particularly to the drawings, designates a container forliquid 2| having submerged therein a pump 22 that is held in operativeposition by the supporting device, designated in general, by 23.

The pump 22 is of the centrifugal type. It is suspended from thesupporting device 23 and has a tubular extension 24 that encases theshaft 25 for the pump impeller 26. The upper end 21 of the extension 24is somewhat enlarged and 1 has a slide fit inan aperture 28 in a plate29 serving as a cover for an opening 30 in the container 20 to which itmay be secured by bolts 3|.

The aperture 28 is located in an off-center positionin the plate 29 andthe plate is provided with a second aperture 32 for the dischargeconduit 33 of the pump. The portion of the discharge conduit extendingthrough said aperture 3.2 is threaded externally for the accommodationof lock nuts 34 that seat against the top and bottom of the plate 29 toassist in connecting the pumping mechanism rigidly to the plate.

' The extension 24 is also secured firmly to the plate 29 andaccordingly has an external annular groove 35 for the accommodation of asplit spring iii ring 36 that seats on the bottom surface 31 of adepression 38 in the upper surface of the plate 29. The portion of thering 36 lying outside of the extension is clamped against the surface 31by bolts 39 that extend through the plate 29 and are threaded into thcasing of the motor 40 driving the impeller for drawing the end of themotor against a seating surface M at the upper end of the extension. Thecasing of the motor in is preferably provided with a boss 42 that liesin the enlarged end of the extension to maintain the motor coaxial withthe pump impeller 26.

In assembling the pumping mechanism on the supporting device, thenlarged portion 21 of the extension and the discharge conduit 33 arefirst inserted in the apertures 28 and 32. The split ring 36 is nextplaced in the groove 35 and the bolts 39 are then placed in the plate 29and threaded into the casing of the motor 40. The motor casing isthereby drawn firmly against the seating surface 4| and the split ringis pressed against th surface 31 to secure the extension to the plate29. The nuts 34 may then be clamped against the both sides of the plate29 for holding the discharge conduit 33 rigid with respect thereto.

From the foregoing description it will be readily apparent to thosefamiliar with devices of the character to which the present inventionpertains that the supporting device may be connected to the pumpingmechanism with a minimum expenditure of effort and time and that theconnection thus effected will remain rigid throughout prolonged periodsof operation of the pumping mechanism.

I claim:

1. In a supporting device for a pump having an extension and a motor fordriving the pump, a support plate for the pump having an aperture toreceive the extension, a member removably and interlockingly engagedwith the extension to seat upon th plate, and a common means forsecuring the motor to the extension and for clamping the member againstthe plate.

2. In a supporting device for a pump and a motor for driving th pump, anextension for the pump having a recess therein, a support plate for thepump having an aperture to receive the extension, a seating surface onthe extension for the motor, a seating member removably and insion toseat upon the plate, and a common means for securing the motor to theseating surface and for clamping the seating member against the plate. I

3. In a supporting device for a pump having an extension and a motor fordriving the pump, a support plate for the pump having an aperture toreceive the extension, a seating surface on the end or the extension forthe motor, a resilient split ring in the outer. surface of the extensionto seat upon the plate, and bolts in the plate threaded into the motorfor securing the motor to the seating surface and for clamping the splitring against the plate.
